websocket(spring官网demo+github官网demo)

## Overview A sample demonstrating capabilities in the Spring Framework to build WebSocket-style messaging applications. The application uses [STOMP](http://stomp.github.io/) (over WebSocket) for messaging between browsers and server and [SockJS](https://github.com/sockjs/sockjs-protocol) for WebSocket fallback options. Client-side libraries used: * [stomp-websocket](https://github.com/jmesnil/stomp-websocket/) * [sockjs-client](https://github.com/sockjs/sockjs-client) * [Twitter Bootstrap](http://twitter.github.io/bootstrap/) * [Knockout.js](http://knockoutjs.com/) Server-side runs on `Tomcat 7.0.47+`, `Jetty 9.0.7+`, or `Glassfish 4.0`. Other servlet containers should also function correctly via fallback options (assuming Servlet 3.0) but they don't support WebSocket yet. Also see the [blog post](http://blog.springsource.org/2013/07/24/spring-framework-4-0-m2-websocket-messaging-architectures/) introducing these features. ### Tomcat 7/8 The app has been tested with this `Tomcat 8 RC10` as well as `Tomcat 7.0.47` which includes a backport of the Tomcat 8 WebSocket support. For Tomcat 8, set `TOMCAT8_HOME` as an environment variable and use [deployTomcat8.sh](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/deployTomcat8.sh) and [shutdownTomcat8.sh](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/shutdownTomcat8.sh) in this directory. For Tomcat 7, you can use `mvn tomcat7:run`. Open a browser and go to <http://localhost:8080/spring-websocket-portfolio/index.html> ### Jetty 9 The easiest way to run on Jetty 9 is `mvn jetty:run`. Open a browser and go to <http://localhost:8080/spring-websocket-portfolio/index.html> **Note:** To deploy to a Jetty installation, add this to Jetty's `start.ini`: OPTIONS=plus etc/jetty-plus.xml OPTIONS=annotations etc/jetty-annotations.xml ### Glassfish After unzipping Glassfish 4 start the server: <unzip_dir>/glassfish4/bin/asadmin start-domain Set `GLASSFISH4_HOME` as an environment variable and use [deployGlassfish.sh](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/deployGlassfish.sh) in this directory. Open a browser and go to <http://localhost:8080/spring-websocket-portfolio/index.html> ### WildFly/Undertow Support available startin with Spring Framework 4.0.1. Requires WildFly 8.0.0.Final. Unzip the WildFly server. Set `WILDFLY_HOME` as an environment variable and use [deployWildFly.sh](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/deployWildFly.sh) in this directory. Open a browser and go to <http://localhost:8080/spring-websocket-portfolio/index.html> ### Using a Message Broker Out of the box, a _"simple" message broker_ is used to send messages to subscribers (e.g. stock quotes) but you can optionally use a fully featured STOMP message broker such as `RabbitMQ`, `ActiveMQ`, and others, by following these steps: 1. Install and start the message broker. For RabbitMQ make sure you've also installed the [RabbitMQ STOMP plugin](http://www.rabbitmq.com/stomp.html). For ActiveMQ you need to configure a [STOMP transport connnector](http://activemq.apache.org/stomp.html). 2. Use the `MessageBrokerConfigurer` in [WebSocketConfig.java](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/src/main/java/org/springframework/samples/portfolio/config/WebSocketConfig.java) to enable the STOMP broker relay instead of the simple broker. 3. You may also need to configure additional STOMP broker relay properties such as `relayHost`, `relayPort`, `systemLogin`, `systemPassword`, depending on your message broker. The default settings should work for RabbitMQ and ActiveMQ. ### Logging To see all logging, enable TRACE for `org.springframework.messaging` and `org.springframework.samples` in [log4j.xml](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/src/main/resources/log4j.xml). Keep in mind that will generate a lot of information as messages flow through the application. The [QuoteService](https://github.com/rstoyanchev/spring-websocket-portfolio/blob/master/src/main/java/org/springframework/samples/portfolio/service/QuoteService.java) for example generates a lot of messages frequently. You can modify it to send quotes less frequently or simply comment out the `@Scheduled` annotation.
